Chemical Structure of o-Xylene
o-Xylene muaj ob pawg methyl txuas rau cov pa roj carbon atoms uas nyob ib sab ntawm lub nplhaib benzene. Qhov no 1,2-kev hloov pauv txawv txawv o-Xylene los ntawm m-Xylene thiab p-Xylene, uas muaj tib lub qauv molecular tab sis txawv txoj haujlwm ntawm pawg methyl.
Cov tshuaj formula ntawm o-Xylene yog C8H10, thiab nws qhov hnyav molecular yog 106.16 g / mol. Nws tus lej CAS yog 95-47-6, uas feem ntau siv los txheeb xyuas cov khoom siv tshuaj lom neeg thiab cov ntaub ntawv lag luam.
Physical Properties of o-Xylene
o-Xylene yog cov kua xim tsis muaj xim nrog qhov kub ntawm qhov kub ntawm 144℃thiab melting point ntawm -25.2 degree. Nws muaj qhov ntom ntawm ib ncig ntawm 0.88 g / cm³ thiab solubility tsawg hauv dej.

Tshuaj Reactions ntawm o-Xylene
o-Xylene tuaj yeem nkag mus rau oxidation thiab electrophilic hloov pauv vim nws lub nplhaib uas muaj ntxhiab thiab ob pawg methyl. Ntawm nws cov tshuaj tiv thaiv kev lag luam, oxidation rau phthalic anhydride yog qhov tseem ceeb tshwj xeeb.
Nyob rau hauv cov txheej txheem no, o-Xylene yog oxidized nyob rau hauv kev tswj tej yam kev mob los tsim phthalic anhydride, ib tug nruab nrab siv nyob rau hauv lub tsim ntawm plasticizers, resins, coatings, thiab lwm yam tshuaj.
o-Xylene Ua li cas?
o-Xylene feem ntau yog rov qab los ntawm cov kwj deg uas muaj ntxhiab hydrocarbon uas tsim thaum lub sij hawm ua roj av. Kev hloov pauv catalytic ntawm roj av naphtha ua kom muaj ntxhiab tsw - cov dej nplua nuj uas muaj benzene, toluene, thiab xylenes.
Txoj kev tsim khoom tuaj yeem yooj yim xws li:
Petroleum Naphtha → Catalytic Reforming → BTX Aromatics → Mixed Xylenes → Separation → o-Xylene
o-Xylene feem ntau tsis yog tsim los ua ib qho kev sib cais los ntawm qhov pib ntawm txoj kev. Nws feem ntau rov qab los ntawm cov dej sib xyaw xylene thiab tom qab ntawd sib cais los ntawm lwm yam khoom.
Kev sib cais yog qhov tsim nyog vim tias o-Xylene, m-Xylene, thiab p-Xylene muaj cov mis molecular tib yam tab sis lub cev sib txawv. Distillation thiab lwm yam kev lag luam sib cais thev naus laus zis tuaj yeem siv tau kom tau txais qhov xav tau xylene isomer thiab purity.
o-Xylene thiab Lwm Xylene Isomers
o-Xylene yog ib qho ntawm peb lub ntsiab xylene isomers, ua ke nrog m-Xylene thiab p-Xylene. Peb lub tebchaw txhua tus muaj cov mis C8H10, tab sis cov haujlwm ntawm methyl pawg ntawm lub nplhaib benzene txawv.
| Xylene Isomer | Lub Npe | Main Industrial Siv |
|---|---|---|
| o-Xylene | Ortho-Xylene | Phthalic anhydride ntau lawm |
| m-Xylene | Meta-Xylene | Tshuaj intermediates |
| p-Xylene | Para-Xylene | Terephthalic acid thiab PET saw |
Mixed xylene txawv ntawm tus neeg isomers vim nws muaj cov khoom sib xyaw ntawm cov tshuaj tsw qab es tsis yog ib qho xylene isomer. Yog li cov khoom siv yuav tsum tau txheeb xyuas los ntawm nws lub npe tshuaj, CAS naj npawb, purity, thiab specification.
Main Industrial Siv o-Xylene
o-Xylene feem ntau yog siv los ua khoom noj rau phthalic anhydride ntau lawm. Nws kuj tseem siv tau los ua cov kuab tshuaj organic thiab ua ib qho nruab nrab hauv cov tshuaj synthesis.
Kev sib txuas nrog phthalic anhydride yog daim ntawv thov tseem ceeb tshaj plaws kom nkag siab thaum ntsuas o-Xylene xav tau. Phthalic anhydride yog siv ntxiv rau hauv thaj chaw xws li plasticizers, alkyd resins, unsaturated polyester resins, thiab coatings.
